1-Carboxymethyl-1′-carboxylatomethyl-3,3′-[p-phenylenebis(oxymethylene)]dipyridinium bromide dihydrate

In the crystal structure of the title salt, C22H21N2O6+·Br−·2H2O, pairs of betaine molecules are bridged by protons (the bridging proton is disordered), forming strong and symmetrical O—H...O hydrogen bonds, leading to an infinite chain along the...
